An MTS file is a video saved in AVCHD format. It is the standard video format used by many Sony and Panasonic HD camcorders. MTS files are also used for storing high-definition video on Blu-ray discs. Xvid is an open-source video codec, and the Xvid-encoded video is typically saved in .avi container format. To convert MTS to Xvid-encoded AVI format, HD Video Converter Factory Pro is a decent choice. Just import the MTS files > select AVI as the output format > start the conversion.
MTS is a form of AVCHD video, and can be directly imported into most non-linear video editors such as Final Cut Pro or Adobe Premiere CS4.Otherwise try a converter like Aiseesoft HD Video Converter (trialware/$29.99 to buy) or check google for a MTS to AVI freeware converter like MTS Converter by Emisoft Studio.
To convert an H.264 video file to AVI format, you can use video conversion software like HandBrake, FFmpeg, or Any Video Converter.

Make sure to adjust any necessary settings such as video quality or resolution before converting.
